This document describes the installation of Power Windows to an XG/H series Longreach. This entails dismantling the motors and servicing them, removing the existing XG/H manual regulators from the doors, fitting the motors and motor arms to existing XG/H manual regulators if necessary, modifying existing E series power window switches, and wiring the system up

Dismantling and servicing the Motors:This is advisable if your motors are second hand units.

Step 1:
Remove the circlip and shim washer from the gear assy.

Step 2:
Remove the gearbox cover assy. See Fig 1. below

Fig 1. Motor assembly with the gear box cover removed.

Step 3:
Remove the gear assy. You should now the motor dismantled as per Fig 2. Ensure the white step down gear has the three retainers (arrowed). If not, youâ€™ll need to fashion up replacements â€“ this stops the gear assy slipping once the window is wound up. 3 pieces of wood dowel with 3 flats works well. Ensure this is sorted as it will save you hassles later.

Step 4:
Remove the white step down gear.

Step 5:
Remove the sealant around the electrical loom grommet and remove the metal P clip and screw.

Step 6:
Remove the two bolts holding the magnet assy & magnet cover.

Step 7:
Carefully withdraw the motor armature, and the magnet assy and cover.
CAUTION: the tip of the armature(worm gear end) has a ball bearing, this should be put aside, along with the ball bearing housed in the armature base (magnet end). The magnet end ball bearing is the larger of the two. Be careful not to damage the brushes when removing the armature.

Step 8:
Remove the brush tension springs. Remove the two Phillips head or hex screws holding the brush assy and cct board to the case.

Step 9:
Carefully withdraw the brush assy and circuit board, just enough the inspect the underside for corrosion and deteriorated wiring. You may need to feed the red and black wires through to assist this. See Fig 3. below.

Step 10:
Using a multimeter, check the continuity of the positive and negative wires to their respective brushes. This tests the overload protector as well, which sits on the underside of the brush assy and circuit board.

Step 11:
Refit the brush assy and circuit board.

Step 12:
Inspect all items for corrosion and deterioration. Clean where necessary.

Step 15:
Insert the larger ball bearing in the magnet assy base â€“ a drinking straw is perfect for this.

Step 16:
Install the brush tension springs, along with the brushes â€“ theyâ€™ll need to be withdrawn in their holders for the armature fitment â€“ paddle pop sticks inserted between the brush pigtail and the brush holder will achieve this.

Step 17:
Smear the upper armature shaft and worm assy with grease, and install into the main case. Remove the paddle pop sticks before pushing the armature fully in.

Step 18:
Install the gasket on the magnet case, lightly smear the armature lower shaft with grease, and install in the magnet assy and case.

Step 21:
Lubricate and install the white step down gear â€“ use it as a guide to adjusting the upper armature preload screw. Give the armature a very slight end play. Donâ€™t overtighten the preload, as this will cause the armature to bind.

Step 22:
Lubricate and install the gear assy with the three retainers.

Step 6:
Remove the door trim by carefully levering the trim from the door frame.

Step 7:
Remove the clear plastic sealing sheet â€“ the adhesive can be cut with a Stanley knife blade.

Step 8:
Drill out the 4 mounting rivets, see Fig 4. below. Youâ€™ll find the easiest way for this is to drill a number of holes around the centre of the rivet, and break the swarf off with pliers. The centre can then be tapped through with a hammer and drift. Alternatively, the usual way is to knock out the centre and drill the centre section out.
CAUTION: The rivets are the main support for the regulator, and as such, the regulator could drop unexpectedly, so provide some support for the window when removing the rivets. A long screwdriver inserted through the inner door skin through the cavity to the outer skin can be used.

Step 9:
While supporting the window, manoeuvre the regulator around to slide the regulator arms out of their respective rails. Remove the regulator.

Step 15:
Repeen the centre pivot â€“ a small damaged socket is good for this, otherwise a ball pein hammer on the edges followed by some centre pops will do the job. See Fig. 8. Peen the areas at right angles to the original peening. Ensure the underside of the centre pivot is supported adequately.

Fig 8.

Step 16:
The bottom piece of the XG/H regulator will need to be cut off with an angle grinder â€“ see Fig 9.

Fig 9.

Step 17:
Install the window motor to the regulator arm with the three 7mm hex screws.

Step 18:
Reinstall the tension spring, ensure there is enough tension â€“ doesnâ€™t need to be much, but needs to be there at full up or down positions.

Step 1:
Fit the two front mounting bolts to the regulator â€“ youâ€™ll need to apply power to the motor, and wind it to full up and down positions.

Step 2:
Wind the motor to mid position.

Step 3:
Fit the regulator to the door, installing the upper arms to the window lower channel mount. This is a bit tricky, as youâ€™ll need to support the window as well.

Step 4:
Fit the regulator lower arm to itâ€™s door mounting rail â€“ it will be easier if the mounting rail retaining nuts are loosened.

Step 5:
Align the regulator two front mounting bolts with the door holes, install the mounting nuts and the two rear mounting bolts and nuts.

Step 6:
Applying power to the winder motor run the window up and down to check correct range of movement and operation.

Step 7:
Tighten all mounting nuts and bolts.

Step 8:
Cut the excess off the 4 mounting bolts, so they donâ€™t foul the door trim when itâ€™s put back on.

Step 9:
Once wiring is completed, Refit the inner plastic, door trim and attaching hardware â€“ installation is a reversal of the removal described earlier.

Wiring up the Power Windows:

This next section describes how to wire up 2 switches per door, but for single switches per window, the individual switch wiring is the same. Fig 11. shows the switch rear and the respective contacts between the terminals during the different switch positions. Fig 12. shows the connections for a single switch setup â€“ the motor connections may need to be swapped to obtain correct movement up & down. Fig 13. shows a dual switch setup.

Fig 13. Dual switch setup.

There is a vacant Power window fuse location, it already has a power line fitted, you can solder your power feed line to one terminal of an E series 30A circuit breaker, feed it through the fuse hole, and plug in your circuit breaker into the fuse panel, see Fig 14. For a single switch fitted to each door, you can use the doorlock actuator power to supply 12v, the wiring is then kept within the door. For console switches only, two wires need to be fed into each door, you should use fuse panel power to supply 12v. For dual switches per door, use fuse panel/door actuator panel power. Ensure you fit wiring connectors so that components can be removed easily, e.g. consoles, window motors, etc. Circuit planning is essential. All power sources mentioned are constant 12v. For best looks and functionality, youâ€™ll probably find the dual switch system to be the best option.

FAQ's:Q: Are LH and RH motors the same?
A: The motor assy itself is the same, but the gear housing is different. LH & RH rear motors can also be used, but not the rear regulators.

Q: Do I need to find new door trims â€“ Will EA â€“ EL trims fit. ?
A: You can fit switches to the existing door trims where the winder used to sit â€“ you only have around 30mm clearance, so the terminals will need to be shortened. The only replacement door trims that will fit are XD/E/F/G/H.

Q: What about fitting an EA-ED centre console with the switches already fitted?
A: You can fit these, and itâ€™s personal preference â€“ I preferred fitting EF/EL switches to match the trim better.

Q: Werenâ€™t Power Windows an option in XG/XH utes ?
A: No, it was never offered in XG or XH Series I or II, or even XR versions or splash utes, unfortunately. But you can self option

Q: One of my motors is a bit noisy when raising the window?
A: Check your window channel adjustment, make sure the window raises and lowers without binding. You may find the motor armature is not up to par â€“ with the motor removed, apply power and put some load on the gearing, if the noise appears, replace the armature. It is handy when you buy your motors to have a spare.

Q: Canâ€™t you fit E series type motors and regulators?
A: No, itâ€™s the easiest to stick with X series motors and regs. If you service your motors properly and ensure the gear assy has minimal slippage as well as ensuring the window adjustment is correct, youâ€™ll find your setup will work well, and have nearly as much refinement as the later E series units. The setup wonâ€™t have the cable troubles of the later units, plus with a two point lift, you should find that window binding/jamming will be minimal.

Q: Iâ€™ve wired in a 2 switch setup â€“ the door switch raises the window when it should be lowering?
A: Swap the motor wire connections and retest.

Q: Iâ€™ve wired in a 2 switch setup â€“ the door switch works okay â€“ the console switch raises the window when it should be lowering?
A: Swap the connections of the two wires that go from the console switch to the door switch.
